Medusa: {} leads to a cluster that doesn't progress and doesn't log.

[Miles-Garnsey]

What happened?

If (like works with Reaper) you put medusa: {} to configure a default Medusa, the cluster fails to progress, and neither logs nor an error condition on the cluster raise the problem to the user's attention. It just fails silently.

Did you expect to see something different?

We should at least log, reject at the webhook, or add an error status to the cluster when this happens.
